Light weight battery??

Not particularly light though are they?
I know the ad said it is for mobility scooters etc, but I hoped the car hadn't read the description. I thought it worth a punt!
I talked to Antigravity batteries about what they would recommend (they do do car batteries too), and they said I should be able to use the one recommended by CycleSi.
They also said Caterham are considering using it a lot more, even as an option.
When it arrives I will fit it and feedback.
ps. It has 480 CCA and 16 Ah, and weighs 1.45kg!!!!! I seriously hope it works!

Please note
You MUST only charge our lithium batteries with a lithium specific battery charger, (such as the Optimate battery chargers offered on this website) the use of any other type of battery charger is likely to damage the battery and invalidate the guarantee.
I presume it fairs ok though with a normal car charging system?You MUST only charge our lithium batteries with a lithium specific battery charger, (such as the Optimate battery chargers offered on this website) the use of any other type of battery charger is likely to damage the battery and invalidate the guarantee.
I think it depends on a number of factors from how it's going to be used. Clearly from the antigravity video it is a recreational bike battery.
Doesn't work if there are likely to be lots of starts as it's low AH.
The whole sales pitch of gazillions of cranking amps is a bit snake oil. You only need what you need, more is not helpful.
I hope the BMS in the battery has low voltage protection so it doesn't die when discharged as that would get expensive.
When I experimented with an Odyssey battery on my k-R500 back in the day, it wasn't successful. I had endless starting problems. Eventually I found that the cranking voltage was too low for the ECU. I went back to the banner and never looked back!
So I had a funky battery case fabricated to locate the battery, had several months of being stuck with a non-starting engine and getting very grumpy to end up with the Banner!!
Anyway, good luck with it and let us know how you get on!

IIRC (long time ago that I installed mine) they are significantly lighter than the more std fayre fitted to cars (and 7s as standard). I'm sure about half the weight.

The Banner 53034, which is commonly fitted, weighs 8Kg. The Oddysey 7Kg.
Upside is no spill. Downside is changing fitting. Not sure it's worth it for 1Kg.
So I am an amateur and don't know much about batteries, but I do have an interest stimulated by thoughts of using Lithium batts for my power tools (see the other thread about my blatchat impact gun). So I've been reading around the subject.
Li batteries are quite susceptible to over charge and over discharge and there are commonly used cheap BMS PCBs to protect multi-cell setups.
It looks like the antigravity batts don't use any kind of protection reading their website. I wonder why that is?

You can ruin the battery if you let it drain to below 10.5 Volts!!! This is true of ANY battery, lead/acid or lithium. Draining a battery to this level will damage the battery cells. This is not a concern if you remember to turn off your ignition, or turn off any accessories that are not ignition switched and monitor your battery if you plan on not riding frequently. You should also make sure your vehicle does not have a “parasitic drain” or “short circuit”. A “parasitic drain” is something like an accessory that is pulling energy from the battery even though the ignition is “off”. This can drain your battery below 10.5V and ruin it. Sometimes a short can also be the cause of a drain on the battery though all accessories are “off”. For the best battery life you should monitor your battery and if you do not ride for a time make sure you disconnect the battery.
I always remove the red battery cut off switch when the car is not in use and when I go back to it to start it/use it, it has always fired up straight away very strongly. I did lots of initial research and liked the look of the quality of the AG stuff so bought one; mainly as I was attracted to the high cranking power and the low weight.
I've bought some rubbish in my time and no doubt wasted good money on things too, but I have to say this AG battery has proved to be one of my better purchases.

Well the Anti Gravity battery turned up!
I was a bit peeved because it is even smaller than the my last failed attempt so there was no way it was going to work.
I started to top the charge up (the charger said it was a little low) but 30 seconds later lost patience, connected it to the car and gave it a go.
It was faultless, a healthy turn over and then it fired straight away!
It defies all logic, did I mention it is smaller than the failed Ebay one!!
Incredible!
